I have a 2017 C-HR and it has an old and bad Toyota Touch 2 and Go (TT2). I've been trying to figure out whether my C-HR TT2 can be replaced with a 2020 model multimedia device. It seems to me that the space and size of the dashboard are the same for both models, so I believe that the installation could be done with reasonable effort. But the suitability of the wiring harness is unclear.

I have asked this thing in Finland Toyota service and Toyota Finland, but always get the same answer: probably the wiring harness does not fit. "Probably" is not a very professional answer, is it?

I do not speak English well enough to search for definite information / pictures on the wiring harness or the 2020 model rear connectors.

Does anyone know of any new infomation about multimedia device (manufacturer, part numbers, etc.).

I know the software is not the same, of course, but the question is how much it has changed. If the navigator is the same as before, the operation (=input data) is probably the same. And I don't think the antenna connections have been changed, nor is the USB connection etc.

It's one problem is that I can't find the part number.

Thanks for the Malc1975 pictures. I look forward to them with interest.
